Physics

The value of $$\dfrac{sin 50^o}{sin 30^o}$$


SOLUTION
The value can be determined as:
$$\dfrac{\sin(30+20)}{\sin(30)}$$

$$=\dfrac{(\sin30\times \cos20)+(\cos30\times sin20)}{\sin30}$$

$$=\cos20+(\cot30\times \sin20)$$

$$= 0.9396926207859 + (1.7320508075689)(0.3420201433257) $$
$$= 0.9396926207859 + 0.5923962654521 $$
$$= 1.532088886238 $$
